So, a jaunt back to the workbench, just to prove I'm not all mouth. While involved in a discussion on an unrelated topic, I was pointed to
http://www.onlinemodels.co.nz/. While
looking at 20 year old master making technology, I also had a look at the pictures of the 3 different phases of
Da. My etched kit is a phase 1(
http://www.onlinemodels.co.nz/diesel.htm#DA1), but sits on a phase 3
mech http://www.onlinemodels.co.nz/diesel.htm#DA3( which on the model is also a Co-Co rather than
AIA-
AIA). So, being a 2' modeler, did this bother me? For some odd reason yes. So, off into the workshop.
Hmm, no
plasticard of the right thickness.
Hmm, that brass strip is the right size, and I need to do more work in brass. 4 Pieces of brass strip 3mm by 33mm were
sweated together with no burned appendages. These were then
marked out and filed to shape. At this point, the flaw in my cunning plan was exposed ( I'll have to find a 6 year old next time to spot it). I was going to need some detail on the
side frames. the most important bits were the central brake cylinder, and the sand boxes at each end of the
bogie. The
side frames were separated, and a piece of brass tube 5mm long was soldered into the
correctish position using a good old Mk1 eyeball measuring implement. a piece of brass square 2mm by 2mm was then filed to shape at the top, and soldered into place, cut and then the
bottom shaped. this was repeated
untill all 4 were done. the SD-7
side frames were modified by carving the old
brake cylinders off, and smoothing the surface of the
bogie frames. the brake rigging was also removed.
This shows the before and after shots. I think its what I was after it still needs the brake actuators added. Maybe if everyone stands back 2'....
